a, Plant hydraulic surface and soil drying trajectory (thick yellow line) simulated25 for exemplary hydraulic parameters and a potential transpiration rate of 4 mm/day. The relation is shown in a as 3-D hydraulic surface and in b from the soil point of view, distinguishing the linear (green) and nonlinear (brown) zones. c,d Exemplary land surface transpiration rate for three contrasting soil textural classes in relation to c bulk soil water potential and d volumetric soil moisture content. The three soils result in different θcrit and ψcrit (dashed black lines) while the evaporative demand is the same (4 mm/day).
